DRIVE MECHANISM FOR DYEING MACHINES.

Application filed April 19, 1922. Serial No. 555,565.

To all whom it may concern:

Be it known that we, JoHN H. Guns and DONALD M. Gross, both residing atPhiladelphia, county of Philadelphia and State '5 of Pennsylvania, haveinvented certain new and useful Improvements in a Drive Mechanism forDyeing Machines, of which the following is a specification.

This invention relates to dyeing. machines in which yarn in skeins isimmersed in a dye liquor. In such machines it is customary to provide adye vatand a reel, or other. device of that character, upon which theskeined yarn maybe mounted. The reel is supported so that it may beraised or lowered relative to the dye vat, and when in the loweredposition, the lower yarn supporting sticks are below the surface of theliquid. Upon revolving the reel the skeins of yarn are immersed in thedye, and suitable provision is made ordinarily so that all parts of theskein may be subjected to the dyeing action. In devices as thus brieflydescribed, driving mechanism is provided by which the reel may berotated and it is herein contemplated to provide a new and improveddriving mechanism together with means by which the source of power forrotating the wheel may be also utilized to lift the reel clearof thevat.

One of the objects of the invention, therefore, is to provide a new andimproved driving mechanism for dyeing machines of the class described,in which means is provided by which the yarn reel'may be raised outof'the' dye vat while being continuously rotated. Q

Another object of the invention is to provide anew and improved drivingmechanism for dyeing machines of the class described, in which the meansfor revolving the reel may be utilized for raising or lowering the yarnsupporting structure relative to the 'dye vat, provision being made forrevolving the reel in either direction of rotation, and at differentspeeds and the elevating mechanism being operable regardless of suchdirection.

Other objects and aims of the invention, more or less specific thanthose referred to above, will be in part obvious and inpart pointed outin the course of the following description of the elements,combinations, arrangements of parts and applications of principles,constituting the invention; [and tail of the clutch for thescope, ofprotection contemplated will be indicated in the appended. claims.

In the accompanying drawings, in which there is shown a preferred formof embodiment of our invention:

Figure 1 shows an end view of the dyeing machine provided with our newand 1mproved driving mechanism.

Figure 6 1s a viewin detail, showing the worm drive for the elevatingmechanism.

1W1th reference now to the drawingain which similar reference charactersdesignate 'similarparts throughout the various views thereof, 1designates a dyeing machine having upright supporting members 2, andenclosing plates 3; Mounted on one end of the dyeingmachine is thedriving mechanism 4-. therefor, supported by a suitable bracket'5.

The-driving mechanism is provided. with a 1 pulley 6 mounted in aprojecting bracket 7, the pulley 6 being driven from any suitable sourceof power. Referring now to Figure 3, it will be seen that the pulley 6ismounted on the shaft 8, supported in suitable ball-bearings 9 in acase 10. At one end of the shaft 8 there is provided a gear 11, ontheinner face of which is mounted a clutch aw 11". .The gear 11 mesh'eswith a corresponding gear mounted on the shaft 13, which'is alsoprovided with gears 14 and 15 rigidly secured. thereto. The gear 14meshes with a small pinion 16mounted on the stud 17 in the casing 10 asbest shown in Fig. 4c, pinion 16 in turn meshing with 'a gear 18, whichis slidable along a shaft 19, but keyed thereto as indicated at 20. Onthe inner face of the gear 18 it is provided with a clutch jaw 18.

It will be seen that the shaft 19 is mounted transmission as used inmotorlvehicles, and

I vanced position.

it will be seen that in the form of transmission herein shown, it ispossible to secure a reverse drive for the shaft 19 by means of causingthe gear 18 to mesh with pinion 16 and therethrough to be driven by thegear 14, or to secure a direct drive of the shaft 19 by moving the gear18 along the shaft until it meshes with the gear 15. By moving the gear18 further along the shaft until the clutch jaw 18 meshes with the jaw11, the shaft 19 will be directly driven from the shaft 8, that is tosay, there will be no reduction in speed between shaft 8 and shaft 19.-Bf," moving the gear 13 to the point in between the: gears 14 and 15, itis possible to stop the rotation of shaft 19, and the structure mountedthereupon, as will be later described, while at the same time permittingshaft 8 to be continuously driven.

. In order 'to secure the speed changes by causing the gear 18 to meshwith different gears on the shaft 13, there is provided in case 10 astud 22,having keyed thereto an arm 23, having a fork 24 in itsextremity, which engages in a groove 25 cut in the hub of gear 18. Thestud 22 is provided with linkage, as indicated at 26, 27 and 28, whichis in turn connected by means of a rod 29 to a handle 30 on the front ofthe machine. By moving the handle 30 it will be seen that the fork 24will be rocked so as to move the gear 18 from its position as shown inFigure 3, to the point where it willmesh with the gear 15, or until theclutch jaw on the gear will engage with the jaw on the gear 11.

Shaft 19, as indicated in Figure 2, extends from one side to the otherof the machine, and is provided with a coupling 31, by which it isconnected to another shaft 32. Shaft 32 passes through a case 33 andslidably mounted on the shaft 32 is one of a pair of clutch jaws 34, theaw 34 being keyed to shaft 32 and revolvable therewith. Corresponding tothe jaw 34 is a similar jaw mounted on a sleeve 36 on which is. keyed abevel pinion 37 within the case 33. The

pinion 3'7 meshes with a corresponding pinion 38, which drives the shaft39, the lower end of the shaft 39 being provided with a worm 40, whichmeshes with a worm wheel 41 mounted on a shaft 42. The jaw 34 isprovided with a groove 43 in which engages a fork 44, operable by meansof a rod 45, a bell-crank 46, a rod 46 and a handle 46 mounted on thefront of the machine, the bell-crank being provided, as is obvious, soas to change the direction of movement of the handle. The rod 46' issuitably pro vided with a spring 46? so that when the handle isoperated, pressure must be maintained upon it, in order that the fork 44will continue to hold the jaw in its, ad-

When the handle 46 is operated, the linked parts will force the jawriphery of one of these heads being provided with teeth which mesh witha pinion 53, mounted on the shaft 49.

It will be seen then that as the pulley 6 is rotated, it communicatesmot-ion in one direction or the other through the gear-shift to theshaft 19, which in. turn.- drives the shaft 49 and causes the reel to berevolved. The

reel 51 is provided with yarn supporting sticks running between theheads in the usual manner, the skeined yarns being supported on thesesticks.

As indicated in Figure 2, the reel 51 is in the lowered position inwhich the lowermost sets of sticks on the reel will pass upon arevolution of the wheel below the surface of the dye liquor, which iscontained in a suitable vat in the lower part of the dyeing machine. Theheads 5252 are suitably supported on a shaft 54, which run in bearingsmounted in the ends of arms 55, these arms being supported at theirother ends on the shaft 49, as shown in Figure 1.

The bearings for shaft 54 are. movable in arcuate slots 56in the endenclosing plates 3 for the dyeing machine, and when the arms are raisedin a manner to be described, the shaft 54 with the yarn support ing reelwill be elevated to a position so that the lower sticks of the reel areclear of the dye liquid. The means for elevating the reel consists ofthe parts'as follows: The arms 55 have pivoted near their middle pointslinks 57 which are in turn mounted at their other ends on eccentric pins58 mounted in gear wheels 59, the gear wheels being supported onsuitable studs in the frame of the dyeing machine, and meshing withpinions 60 mounted rigidlyon the ends of shaft 42. When the clutch aws34 and 35 are engaged, the shaft 39 will be. rotated and this will inturn cause rotation of the gear wheels 59;. This in turn causes thelinks 57 to be raised, carrying the arms 55 and shaft 54 therewith.

By reason of the fact that the shaft 55 is moved in an are about theshaft 49, as a centre, the teeth on the head 52 will continue 111 meshwit-h the pinion 53, so that the reel regardless; of the direction ofrotation of the reel.

Inasmuch as it is a matter of indifference as to which direction theshaft 59 rotates in throwing the link 57, if by any chance the clutchshould not be disengaged when the reel has reached the end of its upwardtravel, no damage will result, inasmuch as the continued revolution ofthe gear 59 will draw the crank downwardly, and thereby lower the reelto its operative position, as shown in Figure 1. As a further safeguard,as has been explained, the clutch control rod 46* is provided with thedisengaging spring 46, so that whenever the handle 4:6" is released, therod 46 will be moved so as to disengage the clutch, and thereby stop themovement of the hoisting mechanism.

In order to assist the movement of the reel, there are provided suitablecounterweights 61, mounted on pulleys 62 on shafts 63, journalled in thetop frame of the dyeing machine, the shaft 63 being connected by asuitable cord 64 with the bearings on the ends of shaft 54.

It will accordingly be seen that we have provided a simple, effectivedriving mechanism for a dyeing machine, well adapted to produce thedesired results and one which will withstand rough and careless usage.In elevating the reel no damage can possibly result if the clutch is notdisengaged at the end of the upward or downward movement of the reel,and it is, therefore,.not necessary to provide automatic stops, or otherdevices of that character, by which to limit the vertical travel of thereel. The reel may be rotated in either direction, as convenient, andthe elevating mechanism is effective either way.

The gear-shift and clutch mechanism are suitably enclosed so as to beprotected. and in turn to protect the operator. While specificarrangements as to the gear-shift, clutch and driving mechanism havebeen indicated, it will be understood that various modified arrangementscan be substituted therefor within the scope of the invention, providedsuch arrangements will permit the continued rotation of the reel ineither direction during its elevation and lowering.
